Clock Drawing Test

The clock-drawing test is used for screening for cognitive impairment and dementia and as a measure of spatial dysfunction and neglect. It was originally used to assess visuo-constructive abilities but we know that abnormal clock drawing occurs in other cognitive impairments. Doing the test requires verbal understanding, memory and spatially coded knowledge in addition to constructive skills [1]. Education, age and mood can influence the test results, with subjects of low education, advanced age and depression performing more poorly [2 4].
